The National Stock Exchange (NSE) has announced that four securities will remain under the futures and options (F&O) trading ban for Thursday, August 14, 2025. These include PNB Housing Finance, PG Electroplast (PGEL), RBL Bank, and Titagarh. The ban has been imposed after these stocks breached the prescribed 95% threshold of the market-wide position limit (MWPL), a level at which the exchange restricts the creation of any new F&O contracts to avoid excessive speculative positions.
Reason for the ban and trading rules
The F&O ban mechanism is triggered when the aggregate open interest for a security crosses 95% of its MWPL. Once this level is breached, the NSE restricts traders from taking any fresh positions in the derivatives contracts of that stock. Market participants are allowed only to reduce or square off existing positions until the stock exits the ban list. This measure is designed to curb volatility, manage excessive speculation, and maintain orderly market conditions.
Impact on traders and market sentiment
For retail and institutional traders, an F&O ban can limit short-term trading opportunities. It also signals heightened activity in the stock, often due to strong speculation or significant news flow around the company. While the underlying cash market for these stocks remains unaffected, the restriction in the derivatives segment can lead to lower volumes in intraday F&O trades and potentially impact liquidity until the ban is lifted.
Historically, stocks in the F&O ban list tend to witness volatility in their cash market trades as participants adjust their positions. Traders closely monitor the MWPL levels to gauge when a stock might be removed from the ban list, as this often results in renewed activity in the derivatives market.
Current scenario
-
PNB Housing Finance: Has been actively traded in recent sessions amid sectoral news and speculative interest.
-
PG Electroplast (PGEL): The consumer electronics player has seen increased participation, likely linked to corporate developments and earnings-related momentum.
-
RBL Bank: The mid-sized private lender remains in focus with heightened derivatives activity in the banking sector.
-
Titagarh: The railway and heavy engineering company has been seeing steady volumes driven by expectations of infrastructure spending.
The F&O ban will remain effective for these securities on August 14, 2025, and will only be lifted once open interest falls below the prescribed threshold. Market watchers will keep a close eye on the MWPL data to see if any of these names exit the ban list in the coming sessions.
